How It Works

Occupancy Detection

An occupant with the Carma app on their phone is detected in close proximity to a Carma Beacon - a small Bluetooth device kept in the glove box.

Trip Tracking

As long as the occupant is detected in the car, the app reports on the total occupancy of the car to the toll agency.

HOV Toll Discount

If the car has passed through a toll plaza, or virtual toll plaza, with 2 or more occupants, the driver is eligible for a high-occupancy toll discount.

Occupancy is in our DNA.

Carma is a world leader in technology that encourages and enables high occupancy commuting. Our mission is to fight traffic gridlock and save people time on their commute by filling up empty seats in private cars. As a trusted partner of federal and state transportation agencies for carpooling, carsharing and occupancy enforcement, we’re helping to drive a smarter and more sustainable transportation system.

BRING CARMA TO YOUR REGION

We work with government transportation agencies to measure and encourage high occupancy travel.
